The CPU is a long-life hardware, and it will not be damaged even when the performance is eliminated under normal use, except in special circumstances.
Intel's first processor chip launched in 1971, officially started to use in 1977, and is still in service with US aerospace equipment. Inferred from the age, this processor has been in service for nearly 42 years, which shows that the processor is really difficult to damage.
So, what exactly can a bad CPU do for dozens of dollars? Can it be repaired and reused?
Why would anyone buy dozens of bad CPUs online?
First of all, I need to explain to you that only Intel and AMD can manufacture desktop or mobile processor chips (my country's Godson has not yet reached the conditions for commercial use). Therefore, the CPU does not have the problem of fake products, and once the CPU is damaged, it cannot be repaired and can only be replaced.
1. The feelings of hardware lovers
Everyone has different hobbies, some like collecting antiques, some like collecting stamps, some like collecting shoes, and a group of digital enthusiasts like collecting various hardware. A good CPU may cost nearly one thousand yuan. Collecting a damaged CPU not only satisfies the feelings, but also costs less. There are even some DIY enthusiasts who turn the purchased CPU into various decorations, such as key pendants and computer desktop decorations.
Second, the fluke psychology of picking up missing
Everyone has a different level of understanding of computer hardware, and misjudgments will occur. For example, if the CPU fan is damaged, frequently restarting or unable to start when starting up, some people will treat it as a damaged CPU. Some CPU bases are bent and can still be used normally after correction. The price is not high, and the income has doubled by a percentage, making some people keen to buy.
3. Disassemble the back cover to make it fake
Although the CPU cannot be repaired after it is damaged, the back cover of the high-end CPU has become a means of illegal profit. Replace the damaged CPU back cover with other models of processors, and profiteers seek violence through the price difference between models. This is also an older method. Now all kinds of detection software are more popular, and few people do this.
Fourth, extract metal
There are certain precious metals in hardware such as CPU and memory, and a certain proportion of metals can be extracted by dissolving hardware devices in batches. However, those who do this are all manufacturers with a certain scale, and they usually purchase in bulk, and don't care about the scattered number of CPUs on the network.
